They began dating, and while considering marriage, they found out about Kikuchi's pregnancy. The couple registered their marriage on November 22.

Kikuchi joined AKB48 in 2006, but she was fired in August 2008 due to a scandal. However, she returned to the group as a Kenkyuusei after passing an audition in December of the same year.

She was also a part of the group's sub-unit Watarirouka Hashiritai, and after she graduated from the group, she started her career as a model.

According to her official blog she will continue working while considering her condition.
